Exoplayer Example
This tutorial will explore simple step by step Exoplayer Examples. It will teach you how to use it to play audio and video. We do this via simple isolated examples created for beginners.
What is Exoplayer?
ExoPlayer is an application level media player for Android.
It provides an alternative to Android’s MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Android’s MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.
Exoplayer Installation
Step 1: Add it as a Dependency
To install Exoplayer declare it as a dependency in your app/build.gradle:
Step 2: Enable Java8
Then enable Java8 if it's not already enabled. You do this in the same app/build.gradle under the android{} closure:
Step 3: Enable multidex
If your Gradle minSdkVersion is 20 or lower, you should enable multidex in order to prevent build errors.
Let's now look at some examples.
Example 1: Simple Exoplayer Example
A simple Exoplayer Example project.
Step 1: Create Project
Start by creating an empty Android Studio project.
Step 2: Dependencies
Add Exoplayer as a dependency in your app/build.gradle:
If Java8 is not enabled please enable it.
Sync.
Step 3: Design Layout
Design a layout to represent the media player component, with buttons for starting, stopping etc as shown below:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
